Application ined Mayas, 1922. 'serial No'. '561,794'.

a citizen ofthe United States, and resident of` Newark, inthe county of 'Essex and State ofNew Jersey, have` invented certain new and useful Improvements in Casters, of which the following is a specification. The invention relates to casters and particularly to casters which are adapted to support furniture or other objects having, Y angle iron or similar flanged legs lor por-l tions to which a caster may beapplied. rlhe term caster is used herein broadly tofinclude furniture slides and the like furniture supporting members.

An object of the present invention is the provision of a simple and effective construction of the character referred to. ln accordance with the invention a member is pro vided in which the lower end of an anglel iron or similar flanged leg or portion of an object to be supported is received. Allele,

ment of the caster or furniture support is inserted within the receiving member between a wall of the same and a surface of the angle iron, the parts coacting in such a manner as to bind them together.

In one form of my construction la member is provided having flanges which embrace the two legs of an angle iron when the latter is inserted therein, this member having a portion which connects the flanges there- K of which extend adjacent to theinner faces of the angle iron. The element of the caster,l

Ysuch as a pintle receiving socket, is driven into the space between the connecting portion of the receiving member referred to and the inner facesof, the angle iron. The

parts are correspondingly tapered'sopthat `when the caster element is forced into position this element, the receiving member and the angle iron, will belirmly bound` together. f

The weight of the furniture or articlesup-k ported will be transmitted directly from the angle iron through its receiving member to the caster element.4 Such a construction may i be manufactured simply and cheaply and may be installed with a minimum 'of time and skill. y Y

Other objects of the invention relate to the provision of improved combinations of parts and details of construction, all as will be more fully described hereinafter. v n

In order that theinventionmay be more clearly understood attention is hereby,l di-' rected to the accompanying drawings form- Fig. 3 is a horizontalsection taken on line y Fig. 4 is a perspective view of the bracket or angle ironreceiving member shownL in the preceding figures;

Fig..y 10 is a plan view of a blank from which another form of receiving member may be made, and Y Fig. 11 is a perspective view of a form of receiving memberv made .fromy the blank shown in Fig. 10. i

Aformed from the blank shown in" lReferring to thedrawings, the lowerend portionk of an angle ironv is shown as'having legs or flanges l, 2. rlhisV angle iron may comprise a leg or other element of an Y article of furniture or other object to be supported. rEhe lower end of the angle iron. is inserted vint-o a receiving member, one form of which, illustrated inrFigs. l

Vto 4, is indicatedgenerally by the reference character 3. Member 3 is shown in reversed positioninl Fig. 4, inforder thatthe Vconstruction may be clearly shown.

Member 3 is preferably formed of sheet I metal and is pressed or otherwise formed to provide portions 4, 4,' .which extend at right'angles to each other from the corner or angle 41. Y i

:The metal `at the 4, yis curved inwardly as shown at 5, 5, flangesl 6,V 6, each extending parallel to one outer ends of flangesi;y 4

i, of the flanges 4 for a distance from the curved portion 5. The inner ends of flanges t5, 6, are joined by a connecting portiony 7 which is preferably curved outwardly about an arc of a circle.

The angle iron` 1, 2, vmay be insertedinto member 3 with the legs of theangle iron extending loosely between parallel flangesl 4, 6. of the receiving member and with the angle or corner 8 of the angle iron received within the angle 41 of the receiving member.. The receiving member is preferably pro.- vided with a pair of lugs or straps 9, 9, each of which extends horizontally yfrom one of the portions 4 of the member arcoss the space between the portion 4 and the portion 6 parallel thereto. These lugs will constitute seats upon which the lower ends of the legs of the angle iron rwill rest. These lugs are preferably formed with endy portions 10 which are bent up and pressed against the outer surfaces of flanges 6 of the member. Y

A vertical element of the caster or furniture supporting` member may be forced upwardly into place between wall 7 of inember 3 and the inner faces of the angle iron. This vertical caster element may and preferably does take the form of a pintle socket or sleeve 11,*having a bead or flange 12 at its lower end. Preferably this socket will be driven into position with a forced fit `so that it will press the legs of Vthe angle iron firmly against the outer flanges 4, 4, of the Vreceiving member and will itself bind firin- `ly against the inner faces of the angleiron,

and the inner surface of the connecting portion 7 of member 3. Preferably socket 11 and portion 7 of the receiving member are provided with a corresponding slight taper. The socket may be driven into position`v as far as it will go in which position the flange or beadv 12 at the bottoni of the socket will abut against the loweiyedges of portions 4 and 7 of the receiving member and against the lower edges of the legs of the angle iron.

ln the construction shown socket 11 is of the top bearing type and is providedwith arched closure 13 atits upper end, it be-y ing understood, however, that the inventionf is 'not limited to this construction. Y Y

"With such a Vconstruction the pintle socket is firmly secured in position within the angle of the angle iron a caster'may be applied thereto whenevei'desircrd by in-y serting the pintle of the caster within the socket. In the construction shown in Figs.

1 and 2 of the drawings, a caster is shown having the usual caster wheel 14 carried by the horn 15, the pintle 16 being secured to the transverse top portion of the hlorn and extending vertically upwardsy therefrom. Any desired means ymay bevemployed for holdiiigthe pintle frictionally within the tioned 909r apart about the periphery of the blank. Blank 31 may be worked by well known means into the cylinder shown lat 3? in Figs. 6 and T having ears 91 extending from-points 90 apart at one end of the cylinder. The cylinder may then be pressed by suitable mechanism into the form shown in Fig. 4 and the ears bent over to form the lugs9 as shown. .V

A. similar receiving socket may be formed from -the blank 3? shown in Fig. 8 which comprises a` rectangular strip with ears 9F extending from one of the side edges. The opposite end edges of the blank are cutaway to provide ears 20, 20, at one end and ears ber shown in Fig. 9, having the flanges 4b,

4b,l 6, 6b, and Vconnecting portion 7" corresponding to the portions 4, 4,. 6, 6, and 'lof the construction shown in Fig. 4.l The ears 9b will be bent over to form supports for the lower end of the angle iron in the same manner as the lugs k9 in the form first described. The ears 20, 2O, and 21,21, at opposite ends of the blank `will be pressed into position in the corresponding recesses at the opposite end of the blank. connection may be made by pressing the ears firmly into position or by welding the lioint, kas desired. 4

.fi modified forni of construction is shown in 11, which may be formed from a blank 3c shown in FiglO. In this form of construction the complete flanges 4, or 4b, of the first two forms of, construction described are omitted, incomplete flanges 4 being provided instead. With this construction one of the flanges 4c is connected by the curved portion 5 of the metal with the parallel flange 6c which is `ioinedL by the curved connecting portion 7C to the other liange 6 which is joined by the other curved portion ,5c to the other partial rear flange 4C.4 Flanges 4c are provided with lugs 9C which are bent across the opening between the lower edges of lianges4 and 6 to form seats for the lower rend of the angle iron in the manner already described. The rblank 3 is provided at its ends with 'ears 9c which 4may be bent into position to form the lugs A firm l, 2, is shown in Fig. 11 as inserted in 'position with its legs extending between the parallel flanges et and 6c of the receiving member. Y

It will be understood that references to angle iron legs or members herein are to be understood as including similar flanged members.

It will be noted that the device described may be used in connection with angle memT bers having considerable variations in the thickness of the metal andthe width ofthe flanges. It is not necessaryV that the legs of the angle iron should extend laterally into contact with the closed end portions 5 of the receiving member, considerable variation in the width of the'angle iron flanges being provided for. Likewisey such variationas is encountered in commercialV practice inthe thickness of the angle liron flanges will be provided for when the cylindrical caster element, such as the socket 11,shown, and the wall 7 of the receiving member are formed with slight tapers, as described. It will likewise be noted that the construction does away with the need of employing screws or rivets, or other additional securing devices for securing the receiving membei` to the angle iron. vantage because of the diliculty which might be 'encountered liny properly aligning such openings in the receiving member and in various forms of angle iron with which the same might be used.

y It should be understood that while I have described certain forms and features of the invention with particularity, the invention is not limited to the exact details which-have been described, but that various modifications may be employed as will be clear to those skilled in the art after reading this specification, the scope of the invention be- This is a particular adber adapted to'receive the lower end of an l angle iron anda pintle sleeve adapted to Y be inserted and frictionally secured, with a forced fit, within said member between a surface thereof and the inner faces of the' angle iron,` said sleeve being adapted to.

press againstsaid surface of the receiving member and a surface of the angle iron sufficiently to bind said member, sleeve, and angle iron together, said sleeve also having a closed top and acting as a pintle-receivingr socket. A

2. In a caster, the combinationof a member adapted to 'receive the lower end of an angle iron, having portions between which the legs of the angle iron may be inserted and a connecting portion opposite the position occupied by the angle of the angle iron, and a vertical sleeve having a closed Vtop adapted to be forced with a wedging action between said connecting portion and the inner faces of the angle iron, to bindv the parts together, and Lto transmit the thrust of the weight carried by the angle iron to the supporting element of the caster. 3. In a caster, the combination of a socket member adapted to fit loosely upon the lower end of an angle iron, and a cylindrical caster sleeve adapted to be forced into place with a wedging action within said socket member and against a surface of the angle iron, to bind said member and angle iron together and to serve as a pintlereceiving sleeve. v

In testimony whereof I have signed ymy name to this specification, at Bridgeport,

Connecticut, on this 12th day of May, 1922.
